Can i run Portal 1+2 on my Acer S7 (Ultrabook)?

Specs are: -3rd Gen Core i7-3517U, 2.0GHz -Intel 4000 Integrated graphics -4gb of RAM -2 x 128gb SSDs in RAID 0 -1080p, although realistically I'd run it at 900 or 768 if necessary Don't plan on taking this on the go, just something to eat away at my time at home, plugged into the wall. I'm no gamer, so any help or advice is much appreciated. Am I wasting my time or is there a way to get a decent frame rate from this?
